Lamb Wave Propagation + Piezoelectricity

[ve1705]

I am trying to simulate lamb wave propagation on Abaqus. The calculation apparently works, but I am wondering why in all step there is 0 displacement.

Here what I am using:
1. Aluminum plate, Property used: Solid extrude, Partition face, Top plate surface, Density, Elasticity Modulus, Global Orinetation, Linear Tet Mesh w/ size 1e-3
2. PZT / Transducer, Property used: Solid extrude, Partition face, Top and bottom PZT surface, Density, Orthotropic Dielectricity, Orthotropic Elasticity, Strain Piezoelectricity, Global Orientation, Linear Tet Mesh w/ size 1e-3
3. Assembly: Both PZT and Plate with CSYS, Step: Dynamic Implicit 1e-4 w/ max. 1000 increment, 1e-7 / time increment, Field Output Req.: Displacement every 1 increment, History Output Req.: EPOT of PZT top surface, Position constraint: Face to face between bottom PZT surface and top plate, coincident point between one point of bottom PZT surface and partitioned top plate, Assembly constraint: Tie between master (bottom PZT surface) and slave (top plate)
4. Amplitude: Tabular Hanning window, Load = 0, BC1: 2 plate edges pinned, BC2: EPOT of bottom PZT surface = 0, BC3: Amplitude of Hanning window * Magnitude on top of PZT surface

I am just wondering what is missing?
Also when I tried to plot XY data from History ODB, there is nothing to be selected from dialog box.

Any suggestion?

Thanks in advance.
